In the use and operation of this device, when hicle which is inclined upwardiy in the usual it is desired to operate the vehicle in the usual manner. A brake pedal supporting shaft. 10 is manner by accelerating the engine, the heel of secured in the frame of the vehicle and. as is the operator is rocked downwardly so as to deusual, extends transversely of the frame. A brake press the heel portion 25 and push the accelerator 50 lever 11 is secured to the shaft 10 in any desired 26 into open position. However. if it is desired to manner, or if desired, may be rockably mounted stop the vehicle by the use of the braking means, on the shaft 10, depending only upon the type the pedal 15 is pushed forwardly and upwardly of braking system which isused in the operation on the floor F with the rollers 23 engaging the of the vehic1e, A bracket 1,2 having a bearing track member 21. This movement of the pedal 15 65 will rockI the lever 11 downwardly and pull the brake rod 14 forwardly so as to compress the brake bands or otherwise operate the braking system.

It will be apparent from the foregoing that an exceedingly `simple brake and accelerator control has been provided whereby in the operation of the vehicle, it will not be necessary for the operator to lift the foot off of the accelerator normally disposed at onelside of thebrake pedal and shift thjefoct ontd the brake pedal'r in order'to stop the'y vehicle. Thisbrakeand accelerator controlling means can be incorporated in present vehicle constructions with only slight changes and with the use of this device, the operator-of the nation with a braking system and accelerator of a vehicle engine, a rock lever, meansfor connecting the rocklever tothe braking system, apedal adapted in' one position to engage said accelerator,

. .a connecting link connecting the pedal with ythe lever, means for pivotally connecting the link to `the lever, means for pivotally connecting the link to .the pedal, a track member adapted to be Imounted on the inclined floor of the vehicle, and

rollers carried by said pedal pivoting means to mount the pedal for movement above the floor ina plane parallel thereto.

2. A device as set forth, comprising in combination with a braking system and accelerator of a vehicle engine, a rock lever, means for connecting the rock lever to the braking system, a pedal adapted in one position to engage said accelerator, a connecting link, means for Vpivotally mounting the pedal on one end of the connecting link, means for rockably securing the other yend of the connecting link to an end of the lever, a slotted elongated plate adapted to engage on the upper surface of the floor. of the vehicle body,

said link projecting through the `slot in the plate,

and rollers carried by the pedal engaging the plate on opposite sides of the slot to mount the pedal for movement in a plane parallel to the surface of the floor.

3. A device as set forth, comprising in combination with a braking system and accelerator of a vehicle engine, a rock lever, an arm carried by one end of the rock lever engaging the braking system, a foot pedal adapted to be disposed on the upper side of the inclined floor of the vehicle body and to engage said accelerator, a link, means for pivotally securing one end of the link to the other end of the lever, means for pivotally securing the other end of the link to the pedal, the floor of the vehicle having a slot through whichthe link extends, a track member disposed on the upper surface of the vehicle oor engaging on opposite sides of the slot, and rollers disposed beneath the pedal engagingthle track on 'oppositej-I sides/f the lslotV to moutgthe pedal for movement in a plane' parallel" to tlf'e'surface 4. A device as set forth, comprising in combinationwith a braking system, and accelerator of a vehicle engine, a rock lever, means for connecting Y the rock lever to the braking system, a rock pedal,

meansfor rconnecting the pedal to the lever, a track disposed below the pedal and engaging the `upper surface of the floor of the vehicle, rollers disposed ,beneath the pedal and engaging the track to mountthe pedal for movement longitudinally 'of the track,and means'for mounting the accelerator rod at a point below one end vof the pedal whereby to move said rod into open `position upon rocking of the pedal in one direction.

5. A ydevice as set forth, comprising in combination with a braking system andaccelerator of a vehicle engine, a rock lever, a pedal, means for connecting the pedal to the rock lever, means for connecting the lever to the braking system, av

track member disposed beneath the pedal, means for mounting the pedal on the track for movement thereover, said pedalcomprising an elongated member, spaced ears carried by the member at a point spaced forwardly from the rear end thereof, said elongated member having a recessed portion adjacent the rear thereof, and an Yaccelerator rod having an end disposed beneath the recessed portion of the pedal, said pedal being normally overbalanced forwardly whereby to raisek the rear end upwardly out of-engagement with the accelerator.

6. A device as set forth, comprising a rock lever adapted to be connected to a braking system of a vehicle, a slotted guide plate, an operating pedal slidably engaging said guide plate, and a link extending through the slot of said plate and connecting said pedal with said lever, said lever when in brake releasing position holding said pedal in a position for engagement with the accelerator of the vehicle.
